The Limestone District School Board (LDSB) has achieved its strongest Education Quality and Accountability Office (EQAO) performance in four years, with gains in every testing category for the 2024-2025 school year. LDSB’s EQAO results align with provincial outcomes in many areas, while showing notable improvements in others and among specific student groups. Limestone’s 2024-2025 results are at, or above, the provincial average in almost all measures.
Results show an upward trend and momentum across all eight areas of assessment for students in Grades 3, 6, 9, and 10, including those with special education needs, underscoring the Board’s intention of making a positive difference in the lives of every student, in every classroom, in every school.
"These results reflect the daily dedication of Limestone educators, educational assistants, program teams, and school leaders,” says Krishna Burra, LDSB Director of Education. “I want to acknowledge the efforts of those who have focused on implementing evidence-informed practices, providing targeted supports, and collaborating across schools to ensure student achievement and success.”
The elementary school report provides assessments of Reading, Writing, and Mathematics written by students in Grades 3 and 6. The secondary school report provides similar information relating to the Grade 9 Assessment of Mathematics and the Ontario Secondary School Literacy Test (OSSLT).

Grade 3 EQAO Results
Grade 3 student achievement saw a 5% to 8% increase in all subject areas in Limestone, compared to the 2023/24 assessment results, with 75% meeting the provincial standard in Reading, 65% in Writing, and 65% in Math.
Results for the province showed a slight increase from the previous year for all Grade 3 subjects and were slightly lower than Limestone across Grade 3 assessment subjects.
This new data shows improvement in all subjects, with Math achievement showing the most significant difference for students in Grade 3.
Of significant note are the gains in achievement in Grade 3 Reading, Writing, and Mathematics made by Limestone students with special education needs – up 9%, 8%, and 9% respectively, compared to the 2023/24 assessment results.
Grade 6 EQAO Results
Grade 6 student achievement in Limestone also continues to build momentum with improvements in all subject areas.
In Reading, 88% of students met provincial standard in 2024/25 – an increase of 9% from the 2023/24 assessment and a higher rate than the province for 2024/25.
Results in Writing showed an increase of 14% over the previous assessment year, with 87% of students meeting provincial standard, at a higher rate than the province.
In Math, results were equal to the province, with 51% of students meeting the provincial standard, an increase of 11% for Limestone compared to the previous assessment year.
Like the Grade 3 assessment results, achievement in all subject areas for students in Grade 6 with special education needs in Limestone has increased, with significant gains in Reading and Writing by 12% and 22%, respectively, since the 2023/24 assessment. This increase in achievement for students in Grade 6 with special education needs is higher than the province by 3% to 10% across all subject areas.
“Limestone students and staff have worked hard to achieve these gains across Reading, Writing, and Mathematics, including the strong improvements for students with special education needs,” says Burra. “The momentum we are seeing is the result of consistent, evidence‑informed practice—targeted instruction, early interventions, collaborative professional learning, and a sharp focus on what happens in classrooms every day.
“We are proud of this progress, and we are committed to sustaining it by continuing the practices that work and adjusting where they do not,” he adds. “Our goal remains steady improvement over time, not one‑year spikes, for every student, in every classroom, in every school.”

We are deepening supports in Grade 9 Math—explicit instruction, daily practice, and timely interventions—and aligning professional learning so teachers have the tools they need. We are focused on building Math confidence and competency for every student.”

“Strong Grade 10 Literacy outcomes begin with strong participation,” says Stephanie Sartor, LDSB Associate Superintendent of Curriculum and Program Services: Literacy Focus. “With 95% writing and 84% successful, up three points from last year, we are encouraged by the trajectory, including the continued improvement for students with special education needs. Literacy is a shared responsibility across subjects, and we will keep pairing explicit instruction with targeted supports so every learner can demonstrate success.”
Students in all publicly funded schools in Ontario are required to write provincial assessments, administered by EQAO, a provincial body that tests students’ skills in Literacy in Grades 3, 6, and 10 and Math skills in Grades 3, 6, and 9 in relation to Ontario curriculum expectations.
Successful completion of the Literacy requirement is one of the requirements to earn an Ontario Secondary School Diploma. The EQAO assessments have undergone significant updates, with the newer digital assessments offered entirely online through a digital platform for students over the past four years.
“The dedication of Limestone educators, educational assistants, program team members, and school leaders will remain foundational to continued efforts moving forward,” says Burra.
